DETAILED DESCRIPTION

[0024] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0025] A heavy-load cargo transport device, such as Figure 1-5 As shown, it includes a heavy-duty bracket 1 and a multi-wheeled trolley 2. Both ends of the heavy-duty bracket 1 are provided with openings 3 for accommodating the multi-wheeled trolley 2. The multi-wheeled trolley 2 can be detachably installed in the openings 3. Figure 1 As shown, when the multi-wheeled trolley 2 is installed in the opening 3, the rollers at the bottom of the multi-wheeled trolley 2 can be used to support the entire heavy-load bracket 1, so as to facilitate the rolling movement of heavy objects such as steel coils, so that the steel coils can be moved from the opening 3 of the container into the depth of the container in a rolling manner, thereby maximizing the use of the space inside the container.

[0026] The heavy-load bracket 1 is provided with a lifting control mechanism 4, which controls the multi-wheeled trolley 2 to move up and down relative to the heavy-load bracket 1. When the multi-wheeled trolley 2 is at the lower dead point, the rollers of the multi-wheeled trolley 2 roll and contact the ground, that is, when it is necessary to control the steel coil to move in the container, the multi-wheeled trolley 2 is lowered to make the rollers contact the ground. When the multi-wheeled trolley 2 is at the upper dead point, the lower end surface of the heavy-loaded bracket 1 is in contact with the ground; when the steel coil moves to the predetermined position, the trolley is controlled to rise, and when the bottom surface of the heavy-loaded bracket 1 contacts the ground, a stable sliding friction contact can be formed, and under the pressure of the steel coil's own weight, the stability of the heavy-loaded trolley 2 placed in the container can be ensured; when the heavy-loaded bracket 1 falls to the ground, the multi-wheeled trolley 2 loses its load, so that the multi-wheeled trolley 2 can be easily removed from the opening 3, so that the multi-wheeled trolley 2 can be easily installed on other heavy-loaded brackets 1 again, and then the steel coil is moved into the container.

[0027] like Figure 6 As shown, the heavy-duty bracket 1 is also provided with a main beam 17. In actual use, the main beam 17 can be used to increase the rigidity of the heavy-duty bracket to avoid bending when loaded. The setting position of the main beam 17 can be as follows Figure 6 As shown, it is arranged at the bottom. In other embodiments, the main beam can also be arranged inside the heavy-duty bracket 1, or arranged on the upper surface, without limitation.

[0028] Specifically, Figure 2 As shown, the lifting control mechanism 4 includes a lifting and fixing frame 5, a cross beam 6, and a jacking mechanism. The lifting and fixing frame 5 is arranged on both sides of the opening 3. The lifting and fixing frames 5 on both sides are provided with lifting travel holes 7 for the cross beam 6 to pass through. The two ends of the cross beam 6 are respectively inserted into the lifting and fixing frame 5 through the lifting travel holes 7. The inner top of the lifting and fixing frame 5 is the jacking upper fulcrum 8. In this embodiment, the upper fulcrum 8 is the cross plate on the top of the lifting and fixing frame 5. The jacking mechanism is arranged between the cross beam 6 and the jacking upper fulcrum 8. The multi-wheeled trolley 2 is located at the lower side of the cross beam 6. The cross beam 6 is restricted by the lifting travel holes 7 in the lifting and fixing frame 5 to move up and down. In order to facilitate the separation of the multi-wheeled trolley 2 from the heavy-load bracket 1, the cross beam 6 is pressed down to connect, that is, the cross beam 6 is pressed against the upper plane of the multi-wheeled trolley 2, and then the cross beam 6 and the multi-wheeled trolley 2 form a whole, and when the two ends of the cross beam 6 are lifted and lowered in the lifting stroke hole 7, the lifting and lowering of the multi-wheeled trolley 2 can be controlled; when dismantling, the heavy-loaded bracket 1 is first dropped to the ground, and then the cross beam 6 loses the heavy-load pressure on the multi-wheeled trolley 2, so that the cross beam 6 can be separated from the trolley. When separating, the jacking mechanism is first released to make the two ends of the cross beam 6 free, and then the cross beam 6 moves axially, so that one end of the cross beam 6 is first pulled out of the lifting fixing frame 5, and the same operation is performed to pull it out from the other end of the lifting fixing frame 5, so that the multi-wheeled trolley 2 can be taken out from the opening 3; the reverse operation can be performed during installation.

[0029] As an embodiment of the lifting mechanism: the lifting mechanism is a jack 9, such as Figure 4 As shown, the jack 9 is placed in the lifting stroke hole 7, the base of the jack 9 is placed on the crossbeam 6, and the free end of the jack 9 is pressed against the upper fulcrum 8. The heavy-load bracket 1 can be lifted by the extension of the jack 9, and then the multi-wheeled trolley 2 can be put on the ground, which can facilitate the movement of the steel coil.

[0030] As another embodiment of the lifting mechanism: Figure 5 As shown, the lifting mechanism includes a fixing nut 10 and a lifting screw 11. The fixing nut 10 is fixedly arranged at the position of the upper fulcrum 8. The lifting screw 11 is threaded through the fixing nut 10, and the lower end of the lifting screw 11 is tightly pressed against the crossbeam 6. The fixing nut 10 is arranged at the position of the upper fulcrum 8, and the upper fulcrum 8 is provided with an opening corresponding to the nut hole of the fixing nut 10, so that the lifting screw 11 can pass through the upper fulcrum 8, and the lifting and lowering of the multi-wheeled trolley 2 is controlled by the rotation of the lifting screw 11.

[0031] As an improvement, the lifting and fixing frame 5 is detachably mounted on the heavy-load bracket 1. In actual use, the detachability of the lifting and fixing frame 5 can be utilized. When it is removed from the heavy-load bracket 1, the upper surface of the heavy-load bracket 1 can be formed into a flat surface, and the flat surface can be used to carry other goods. For example, when machine tools and other goods are transported in containers, the flat surface can facilitate the placement of the machine tools.

[0032] Furthermore, it also includes a rolling limit device, which includes limit blocks 12 arranged on both sides of the steel coil, and the limit blocks 12 are arranged on the heavy-duty bracket 1 in an inverted V-shaped structure. Figure 1-5 As shown, one side of the limit block 12 is attached to the circular surface of the steel coil, thereby limiting the rolling of the steel ring. In actual use, the limit block 12 can be fixed by welding or bolted, so that the limit block 12 can be easily disassembled. In other embodiments, a slot is provided on the heavy-duty bracket 1, and a corresponding plug is provided at the bottom of the limit block 12. The bottom of the limit block 12 is inserted into the slot for quick installation or disassembly.

[0033] Furthermore, a slip limiting device 13 is included, and the slip limiting device 13 is arranged at both ends of the steel coil, and includes a limit rod 14, and the limit rod 14 is vertically arranged on the heavy-duty bracket 1. The limit rod 14 blocks both ends of the steel coil, which can well prevent the axial sliding of the steel coil; in actual use, the limit rod 14 can be arranged in a form that is easy to plug and unplug.

[0034] Furthermore, the four corners of the heavy-duty bracket 1 are provided with anti-collision corner guards 15. Figure 1 , 3As shown, the anti-collision corner guard 15 is chamfered and can be wrapped with a rubber pad similar to a shock-absorbing pad on the outside, so as to prevent the heavy-duty bracket 1 from crashing into the container when moving. The heavy-duty bracket 1 is also provided with a binding fixing point 16. The binding fixing point 16 is as shown in FIG. Figure 3 As shown, a steel wire rope can be passed through the center hole of the steel coil, and then both ends can be fixed to the binding fixing points 16; the binding fixing points 16 can also be connected and fixed to the inner wall of the container to prevent the entirety from moving in the container.
